MagnaFlow 54955 Catalytic Converter - Front Left or Front Right

Universal Federal Catalytic Converter

MagnaFlow catalytic converter 54955 is a universal Standard Grade replacement built for Federal/EPA-compliant applications outside California. Its stainless steel spun-body construction, ceramic substrate, and welded inlet and outlet connections support corrosion resistance and efficient exhaust flow.

This part is a fitment-based solution for select applications that require cutting and welding during installation. It is listed for 2007 Lincoln Town Car front left and front right applications, plus 2000-2005 Volkswagen Passat applications. The compact round body measures 9.75 inches long with 2.25-inch inlet and outlet diameters.

Key Features

• Universal catalytic converter with weld-on inlet and outlet connections
• Stainless steel body and tube construction for corrosion resistance
• Ceramic substrate with a spun round body design
• Federal/EPA compliant for pre-OBDII federally registered vehicles
• Compact low-mass layout for improved thermal efficiency

Detailed Description

MagnaFlow 54955 is part of the Standard Grade Universal Federal line, a product family focused on universal-fit exhaust replacement for regulated applications. The design uses a stainless steel spun body with a ceramic substrate and straight, weld-on 2.25-inch inlet and outlet connections. That combination makes it suitable for exhaust systems that require fabrication rather than direct bolt-on replacement. MagnaFlow 54955 is engineered to meet or exceed Federal emissions requirements for EPA-regulated use, and the stainless construction helps resist corrosion in demanding exhaust environments.

For buyers searching for a MagnaFlow catalytic converter 54955 for a Lincoln Town Car or Volkswagen Passat, this unit provides a universal replacement path where the original converter must be matched through cutting and welding. The round body and compact dimensions help package the converter within custom or repair-based exhaust work.

What It Is Used For

• Replacing a worn or failed catalytic converter in a fabricated exhaust repair
• Addressing check engine light concerns related to converter efficiency
• Restoring exhaust after converter damage, corrosion, or internal substrate breakdown
• Meeting Federal/EPA emissions requirements on qualifying applications
• Supporting exhaust system repairs that require weld-in installation

Installation Notes and Tips

Installation requires cutting and welding. This is a universal catalytic converter, so fitment must be matched to the exhaust system dimensions and application requirements before installation. The unit uses weld-on inlet and outlet connections, and no mounting hardware, gaskets, clamps, or hangers are included. Confirm the 2.25-inch inlet and outlet sizing and the available space for the 9.75-inch body length before beginning work.

Quality Assurance

MagnaFlow 54955 is built as a Standard Grade Federal/EPA-compliant catalytic converter for regulated exhaust service. Its stainless steel construction, welded body design, and ceramic substrate reflect MagnaFlow’s focus on emissions replacement parts for universal applications.
